EXTENDING THE APPLICABILITY OF SOFTWARE DSM BY ADDING USER REDEFINABLE MEMORY SEMANTICS

摘要

This work seeks to extend the applicability of distributed shared memory (DSM) systems by suggesting and testing an extended functionality "User Redefinable Memory Semantics" (URMS) that may be added to most DSM systems. We show how URMS is included with one DSM system, PastSet, and sketch the applicability and ease of use of URMS for a set of current applications. Finally, a micro-benchmark of URMS on PastSet, show performance gains of 79 times over a naive DSM model, 48 times over a tuple based DSM model and 83% over MPI.
